PURPOSE: To improve operation efficiency by installing a bucket section to the rear section of a truck travelling a conduit, providing the front section of the bucket section with a scraping means for soil and sand, etc. and mounting a suction pump to an end section in the travelling section of the truck.
CONSTITUTION: When a which 2 is wound, a winch 3 is rewound and a truck 1 is moved backward only by a predetermined distance (a) in a sewage conduit 7, a bucket wall 1B' is turned upward by the passage of soil and sand, etc., and a scraping member 1C is floated from the bottom of the conduit 7. When a winch 43 is wound, a winch 42 is rewound and the truck 1 is shifted forward, the scraping member 1c scrapes soil and sand, etc., and the bucket wall 1B' forms a weir and pushes out muddy water containing soil and sand, etc. to the suction pump 6 side, storing muddy water by a bucket section 1B. Muddy water is carried out to treaters 9 by the pump 6. The forward and backward movement of the truck 1 are repeated, and soil and sand are all pushed out to the pump 6 side.
